To all whom it may concern:

Be it known that I, LUUIS DnsoAMrs, a citizen of the Republic of France, residing in Chatcauroux, Department 01 Indie, France, have invented certain new and useful Improvements in Apparatus for I the Manufacture of a Mixture of Sulfur Dioxid and Nitrogen, of which the following is a specification.

This invention is for the purpose of obtaining a mixture of sulfur dioxid and nitrogen, industrially free from oxygen. The mixed gases free from oxygen, obtained by a perfect combustion of sulfur in air, may be applied for any useful purpose, for example, the manufacture of hydros'ulfites with utilization of the residuary nitrogen.

To secure perfect combustion of the sulfur in the oxygen of the air the proportion of dry air introduced into the i'urnaee is adjusted, the air is heated suitably before the combustion, and the heated air is brought in a thin layer in contact with the burning and molten sulfur, so that the temperature attained is suitable for completely convertin all the oxygen into sulfur tllUXlt The construction of apparatus furnace suitable for the process just described, will be well understood from the accompanying drawings which show an example of the furnace.

Figure 1 is a vertical section and Fig. 2 a plan.

The circular furnace comprises three essential parts: an air heating chamber A, a sulfur pan B, and a combustion chamber C.

The sulfur is introduced into the chamber C through a charging door K which is then closed hermetically. An orifice closed by a screwstopper O affords a passage through which the sulfur may be ignited. .he suliiur melts rapidly and. collects as a liquid layer in pan B. The charge of sulfur introduced through K such that the level of the liquid sulfur is never above the level at n.

The atmospheric air, as dryas possible,

and adjusted in quantity by any suitable known dcvice, is admitted by the pipe i); it is heated by passing along the chamher A past the circular baille plate E, and then flows through the vertical. pipe 1*. As it leaves this pipe, the air is reflected on to the bath of liquid sulfur B by a circular cap H supported by feet I. The hot air in Patented Jan, 2%, 191%.
